Prices rose 26 percent in Nevada to lead all states. It was followed by California (20.2 percent), Arizona (16.9 percent), Hawaii (16.1 percent) and Oregon (15.5 percent).
CoreLogic also says prices rose 2.6 percent in May from April, the fifteenth straight month-over-month increase.
Steady hiring and low mortgage rates have encouraged more Americans to buy homes. Greater demand, a limited number of homes for sale and fewer foreclosures have pushed prices higher. Prices are still 20 percent below the peak reached in April 2006, according to CoreLogic.
Sales of previously occupied homes topped the 5 million mark in May for the first time in 3½ years. And the proportion of those sales that were "distressed" was at the lowest level in more than four years for the second straight month. Distressed home sales include foreclosures and short sales. A short sale is when a home sells for less than what is owed on the mortgage.
Home sales are expected to increase in the coming months. That's because the number of people who signed contracts to buy homes rose in June to the highest level since December 2006. There's generally a one- to two-month lag between a signed contract and a completed sale.
One worry is that higher mortgage rates could slow the housing recovery. Still, rates remain low by historical standards. And increases in rates could boost home sales. That's' because many Americans may act to lock in the lower rates before they rise further.
Rates have been trending higher for two months. And the average rate on a 30-year fixed mortgage leaped to 4.46 percent last week, according to mortgage buyer Freddie Mac. That's the highest in two years and a point more than a month ago.
Mortgage rates surged after Federal Reserve chairman Ben Bernanke said last month that the Fed could scale back its bond buying later this year and end it next year if the economy continued to strengthen. The bond purchases have kept long-term rates down.
Economists say that higher mortgage rates are unlikely to stifle the housing recovery. A more critical issue is whether potential buyers can get loans. There are signs that banks have become more willing to extend mortgages.

The original California capital has come a long way from its farm town origins. Today, San Jose is the center of Silicon Valley. And the area, including Sunnyvale and Santa Clara, is home to some of the world's biggest tech companies, including Apple, Hewlett-Packard, Intel and Google. Such employers tend to reward their geeks handsomely. Google even keeps its interns well-heeled, paying those specializing in software engineering an average $6,432 a month, according to employment research firm Glassdoor. The hefty paychecks can help cover housing costs — the San Jose area's median home value is the highest on this list, and a whopping 20.8% of houses are worth $1 million or more, compared with just 2.3% of all U.S. homes.

Beautiful beaches and top-drawer retailers lay out the welcome mat for thousands of millionaires, as well as leisure travelers, who flock south for the warmth of the Gulf Coast.

You can get a glimpse of the local wildlife a short drive away at Everglades National Park and Ten Thousand Islands. While real estate in the area tends to become more affordable as you move inland, the median value of homes in prime coastal locales such as Pelican Bay and the City of Naples is about $800,000.

The southwest coast of Connecticut, stretching from Bridgeport to the border with New York, provides a perfect (and preppy) suburban base for high-powered commuters, many of whom work and play in nearby Manhattan. Nearly 34,000 residents, or 8.1% of the local labor force, are employed in management positions, earning about $68 per hour on average. And 16.7% of households report an annual income of $200,000 or more; only 4.5% of the country's households pull in that much each year. Those high paychecks can help cover the area's high costs. Stamford proper is one of America's most expensive big cities, and typical homes in small affluent towns such as Greenwich and Darien go for $1 million.
This tiny New Mexico town has the smallest population, as well as the highest concentration of millionaires, on this list. Chalk up the density of affluence to the National Laboratory, a research facility focused on national security and the county's largest employer. Since the lab was established in 1943 as site Y of the Manhattan Project, it has drawn some of the world's top scientific minds with state-of-the-art facilities, currently including more than 1,200 buildings on a 36-square-mile campus, and generous paychecks. In fact, the area's six-figure median household income is the highest on this list. And relatively low living costs — just 2.9% above the U.S. average — will help wealthy residents hold on to their fortunes.
